Abstract
A fan includes an inlet part disposed to form a fan inlet, a base disposed to form, together with the inlet part, a fan outlet, and a blade. The blade extends from the base to the inlet part, and includes a first guide surface having an inclination toward an outside of the fan in a radial direction of the fan which changes in a direction from the inlet part toward the base, and a second guide surface having an inclination toward the outside of the fan in the radial direction which changes in a direction from the base toward the inlet part.
Claims7
A fan, comprising:
- an inlet part disposed to form a fan inlet;
- a base disposed to form, together with the inlet part, a fan outlet;
- and
- a blade extending from the base to the inlet part, the blade including:
- a first surface formed to face outward in a radial direction;
- and
- a second surface formed to face inward in the radial direction, the second surface including:
- a first guide surface having an inclination toward an outside of the fan in a radial direction of the fan which changes in a direction from the inlet part toward the base;
- and
- a second guide surface having an inclination toward the outside of the fan in the radial direction which changes in a direction from the base toward the inlet part;
- and
- a stepped portion formed at a boundary between the first guide surface and the second guide surface, the stepped portion including:
- a first stepped portion having a surface which faces the first guide surface;
- and
- a second stepped portion having a surface which faces the second guide surface.
An air conditioner, comprising:
- a housing;
- a heat exchanger disposed inside the housing;
- and
- a fan configured to suction air to an inside of the housing and discharge the air to an outside of the housing, the fan including:
- a fan motor;
- an inlet part through which air introduced to the inside of the housing is introduced;
- a base to which the fan motor configured to rotate the fan is mounted, and
- a blade extending from the base to the inlet part, the blade including:
- a first surface formed to face outward in a radial direction;
- and
- a second surface formed to face inward in the radial direction, the second surface including:
- a first guide surface inclined in a first direction;
- a second guide surface inclined in a second direction different from the first direction;
- and
- a stepped portion formed at a boundary between the first guide surface and the second guide surface, the stepped portion including:
- a first stepped portion having a surface which faces the first guide surface;
- and
- a second stepped portion having a surface which faces the second guide surface.
